JAR-CLOSURE Specification Letters Patent.

Patented Dec. 22, 1908.

To all whom it may concern:

Be it known that I, ALFRED (J. .MoCLos- KEY, a citizen of the UnitedStates, residin at Philadelphia, county of Philadelphia, an State ofPennsylvania, have invented a new and useful Improvement in Jar-Closures, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, whichform a part of this specification.

The object of my invention is to provide a closure for a jar adapted forthe reception of preserves, condiments, canned goods and the ike, whichwill absolutely exclude the ingress of air so as to preserve thecontents indefinitely, and which may be readily removed and replaced.

It is also my object to provide a closure having the foregoingcharacteristics which will be simple in construction and inexpensive tomanufacture.

These objects are attained in the closure illustrated in theaccompanying drawings, in which Figure 1 is a perspective view of thejar sealed and covered and with fastener a plied to the lid. F i 2 is avertical sectiona view of the same, Fig 3 is a perspective view of the,closing cap. Fig. 4 is a perspective view of the asket. Fig. 5 is aperspective view of the astener for the lid.

The inner wall of the jar or is cut away circumferentiall at its to toform an annular ledge or shou der 1). T 1e jar is swelled outwardly nearits top to form a projection 0 having a flat upper surface or ledge (1whose width is increased by reducing the thickness of that part of thejar above the projection.

The cap comprises the base e from the periphery of which projectsupwardly the rim f. From the up er edge of the rim projects outwardlythe ange 9, having an annular shoulder or led e 7' near its perlpheryfThe base 6 is of a s 'ghtly curved form so as to form a concavity in itslower face.

\ center ofthe base is a small orifice h prefercork or rubber.

ably surrounded by a flange on the upper face so as to extend the lengthof the orifice and ada tit to receive a cork or stopper i preferab y ofcom ressible material such as is a asket of cork, rubber, or othercompressil ale material adapted to surround the rim f and underlie theflange g.

The cap is applied in the following man- In the.

nera The jar is substantially filled with the preserves, which should behighly heated.

Thecap is..

when-introduced into the jar.

then a plied to the jar, the rim f and gasket k exten ing within thejar, and the ca is, pressed down into position. The part 0 the,

gasket below the shoulder b is thus compressed between the 'ar and cap,while theupper-part of the gas et is forced or bulged outwardly by theshoulder 7' so as to partly overlie the shoulder 1'), thus forming atight joint between the cap and jar. The application of the cap willdisplace the excess of preserves upwardly and cause it to exude from theorifice h. The stopper '8 is then insertedthe cap, all that is necessaryis to insert the blade of a knife or other convenient edged tool betweenthe flange g and the up er edge of the jar. Owing to the bevel of th erim when once one edge of the cap is slight y raised, the joint isbroken and the vacuum relieved, and vei little additional force isrequired to entire y remove the cap.

After the cap is applied as described, the flanged lid Z is placed onthe jar so that the lower edge of its flange rests above the ledge d. Tohold the lid in position, there is provided the fastener shown in Figs.1 and 5, which is com osed of a single plece of wire. This-wire is entto form a central curved oke m, from each end of which the wire is ent uwardly, as at n, thence horizontally forwar l as at o, and thencedownwardly, as at p, t e last named downward bends having their extremeends bent somewhat backwardl The wire is made of sprin metal, and t ehorizontal bends conver c 50111 the yoke toward their free ends. he edgeof the lid Z is cut away at r, Fig. 1, so that, when the jar is in use,the lid may be applied to the jar, while the bowl end of a spoon remainstherein, the shank or handle of the s oon projectin through the recess1' in the li To app y the fastener, the free ends of the fastener areforcibly separated and the fastener ap lied to the jar, as shown in Fig.1, so that the yoke m underlies the projection c,

the bends 0 overlie the lid, the bends n and 7), e'xtend alongside theprojection c and the flange of the lid while the extreme ends of thebends extend under the projection 0.

Owing to the elasticity of the wire and the I tendeney of the free endsof the fastener t0 spring together, the lid will be held on the jar byboth a dmx'mx'ard pressure and a lateral Y pressure. ends thereof aremerely sprung further apart and the fastener slipped otl.

Having now fully described my invention, what I claim and desire toprotect by Let-- P teis Patent is:

1. "the combination with a jar whose Wall is narrowed near its upperedge to form an 1 To remove the fastener, the free 1 compressible gasketadapted to surronnd the rim and be confined by the rim and flangeagainst the inner wall of the jar so as to partly overlie said ledge.

2. The combination with a j ar Whose outer wall is out awe y to form anexternal annular ledge, of a compressible gasket adapted to be confinedagainst the inner wall of the jar, a cztp comprising an oritieed baseand an lipwardly and outwardly extending riin adapted to so eontlnesaidgasket, a stopper adapted to close the oriiice in the cap, and a lidadapted to overlie the cap and having a depending annular flangeextending outside the cap rim and adapted to overlie the said ledge.

In testimony of which invention I have hereunto set my hand, atPhiladelphia, on

this 23rd day 0 December, 1907.
